I think I had some variant of that April 1 worm back in Dec & Jan (yes, twice). Although I had to deal a rep in India, my problem was fixed remotely. It was deep and vicious and even with the McAfee plan, still cost me money, but I can’t complain about the work they did.
I only found out recently that my university gives us Norton for free. I put it on my laptops, but once my McAfee subscription runs out, I might should change to Norton.
Abort! - abort! - abort!
Do not go there. You'll be sorry.
There are plenty of very good anti-virus programs that won't bog down your computer by hogging all the resources like Norton will.
See post #29. Avira anti-virus. I use it. It’s good. It’s free.
